TO ME...the .40 is a much snappier round and harder to shoot quick strings of fire than the .45...Not unbearable by any means, but there is no advantage to the .40 as far as ballistics...it's a little cheaper than the .45 and has a higher capacity...but if that's what you're looking for, go with the 9. The M&P is VERY sweet platform though, the cool thing especially with the .45 M&P is that you can toss the small backstrap on and still get a great grip on it if you have smaller hands whereas a lot of people have a tough time gripping a larger .45 grip. If anyone tries to tell you about hydrostatic shock regarding pistol rounds don't believe them, they're isn't enough velocity for it occur (except the FN 5.7 round) so velocity doesn't really help.
Bear in mind, anytime you talk caliber people get all uptight about it...I have both a 9 and a .40, shoot them both well, they'll both drop someone if need be, so in the end get whichever you like better and practice with it and you'll be golden.

honestly nothing will be better if you cant place your rounds. I personally have a .38sp, 9mm, and a 45ACP. I don't carry three extra mags with me because I believe I shouldn't have to use extra mags if the need should come. I carried all three calibers but I prefer the .45. I carry the 9mm when the attire doesn't allow for a big frame.
I went with a .40 for the cheaper ammo and capacity. The recoil is noticeable but not unmanageable. I carry 11 in the compact mag and a 16 round back up mag. If 27 bullets don't get me out of trouble it wasn't meant to be.
I personally love the .40. I shoot it very well and I don't notice significantly more recoil than 9. I like 45, but regardless of platforms I have never been able to achieve anywhere near the accuracy I have with 9 and 40. I've had a RIA 1911 (sold), Glock 30 (sold), and now a Glock 36 (that collects dust). I shoot my XD40sc better than anytthing else and I have 6 mags. I shoot it dead-eye from distances all the way out to 50 yards. From 10 yards it is silver dollar sized groups in rapid fire and double taps. Why should I carry anything else?
45 is also expensive to shoot and .40 is barely more than 9. It just fits my needs very well, so I'm going with it.

40S&W is more expensive 9mm with minimal benefits. It's up to you if you want the capacity of a 9mm or a 45 that may make bigger holes as so many like to argue.
I'll stick with my 9mm. I've got a 45ACP but have carried it twice. I'll never get rid of it but for carry, I'll take 9mm over 45 or 40 any day
I don't carry a gun to look for or start a fight. I carry one to finish a fight I never wanted to be in.

I still love my .40!

The .40 is the perfect round for me on my primary EDC, of which is an XD. I think it's a great compromise between the 9mm & the .45ACP, and I shoot the best with it for my EDC and my alternate BUG, XDsc.
For me it was a negotiable stopping power avg result, capacity, accuracy, and price. I personally don't notice the "snappy" recoil that others comment on (maybe it's platform related), but know I enjoy shooting my .40XD & .40XDsc a whole lot longer than I did my G21.
To each their own. Try each caliber on multiple platforms before committing to a purchase.
